What is an AI chief of staff?

Opitor is an AI-native operating system for small companies, where every person gets their own AI chief of staff. This page says what we mean by that: what the chief of staff does, what it never does, and how it differs from other software that uses the same name.

A chief of staff works for one person

A human chief of staff works for one leader. They read what comes in and decide what needs that person’s attention. They chase the things that were promised. They keep the longer goals in view while the day fills up with small things. They advise, they draft, and they never sign in the leader’s name.

An AI chief of staff is that role, run by software, for one person. It is not a shared tool the whole team prompts, and it is not a chat window where you type one task at a time. It lives where your work happens and works from what it sees there.

In Opitor, every person gets one

Many products that use the phrase give a chief of staff to one executive. Opitor gives one to every person in the company: the founder, the salesperson, the engineer, the person who joined last week. Each chief of staff works for its own person, sees only what that person can see, and keeps a memory that only that person can confirm or delete.

That is why we call Opitor an operating system rather than a tool. Messages, todos and memory are part of the same product, and the chief of staff works across them instead of being bolted onto something else.

What it does

What it never does

How this differs from other software with the same name

One per person, not one per executive. The point of Opitor is that the whole company runs this way, so the salesperson’s chief of staff and the founder’s chief of staff are the same kind of thing.

Inside the system, not on top of another tool. Because messages and todos are Opitor modules, the chief of staff does not need to be connected to five other products to see your work.

Drafts only. Many tools in this category can send messages once you approve them, and some act on their own. Opitor’s chief of staff never sends anything. You do.

Who it is for

Small companies and the founders who run them. You start alone, invite your team when you are ready, and run the company on it.
